Not all of the humans converted into Cybermen during the last invasion
were killed. One has survived, and she used to be Ianto's girlfriend,
Lisa. Now half-human and half-Cyberman, Lisa has been hidden in the
bowels of the Torchwood Hub until Ianto can find a way to restore her to
the way she was. But can Lisa really be saved -- or is she lost to him
forever?

Production

Cyberwoman -- originally called “The Trouble With
Lisa” -- marked head writer Chris Chibnall's second scripting
contribution to Torchwood, following Day
One. It was directed by James Strong, who had helmed The Impossible Planet / The
Satan Pit for Doctor Who's 2006 season. Cyberwoman
was part of Torchwood's third production block, joining They Keep Killing Suzie.
